activity各种方法在点击时的区别

标签：android   activity   生命周期   

用到不同方法时候某些系统有不太一样的情况：

public class MainActivity extends Activity {
	private static String TAG = "MainActivity";

	@Override
	protected void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		setContentView(R.layout.activity_main);
		Log.i(TAG, "onCreate");
	}

	@Override
	protected void onStart() {
		// TODO Auto-generated method stub
		super.onStart();
		Log.i(TAG, "onStart");
	}

	@Override
	protected void onRestart() {
		// TODO Auto-generated method stub
		super.onRestart();
		Log.i(TAG, "onRestart");
	}

	@Override
	protected void onResume() {
		// TODO Auto-generated method stub
		super.onResume();
		Log.i(TAG, "onResume");
	}

	@Override
	protected void onPause() {
		// TODO Auto-generated method stub
		super.onPause();
		Log.i(TAG, "onPause");
	}

	@Override
	protected void onStop() {
		// TODO Auto-generated method stub
		super.onStop();
		Log.i(TAG, "onStop");
	}

	@Override
	protected void onDestroy() {
		// TODO Auto-generated method stub
		super.onDestroy();
		Log.i(TAG, "onDestroy");
	}

	@Override
	protected void onSaveInstanceState(Bundle outState) {
		// TODO Auto-generated method stub
		super.onSaveInstanceState(outState);
		Log.i(TAG, "onSaveInstanceState");
	}

	@Override
	protected void onRestoreInstanceState(Bundle savedInstanceState) {
		// TODO Auto-generated method stub
		super.onRestoreInstanceState(savedInstanceState);
		Log.i(TAG, "onRestoreInstanceState");
	}

	@Override
	protected void onNewIntent(Intent intent) {
		// TODO Auto-generated method stub
		super.onNewIntent(intent);
		Log.i(TAG, "onNewIntent");
	}

	@Override
	protected void onUserLeaveHint() {
		// TODO Auto-generated method stub
		super.onUserLeaveHint();
		Log.i(TAG, "onUserLeaveHint");
	}

}

1.note2和盖世2：启动流程部分不同。红色标出

10-25 21:24:58.990: I/MainActivity(17527): onCreate
10-25 21:24:58.990: I/MainActivity(17527): onStart
10-25 21:24:58.995: I/MainActivity(17527): onResume

主界面按返回键：

10-25 21:25:25.290: I/MainActivity(17527): onPause
10-25 21:25:25.485: I/MainActivity(17527): onStop
10-25 21:25:25.485: I/MainActivity(17527): onDestroy

主界面按menu键

10-25 21:26:05.650: I/MainActivity(17527): onUserLeaveHint
10-25 21:26:05.650: I/MainActivity(17527): onPause
10-25 21:26:06.800: I/MainActivity(17527): onSaveInstanceState
10-25 21:26:06.800: I/MainActivity(17527): onStop

再进入：

10-25 21:27:13.050: I/MainActivity(17527): onRestart
10-25 21:27:13.050: I/MainActivity(17527): onStart
10-25 21:27:13.050: I/MainActivity(17527): onResume

按电源键：

10-25 21:27:43.355: I/MainActivity(17527): onPause
10-25 21:27:43.360: I/MainActivity(17527): onSaveInstanceState
10-25 21:27:43.360: I/MainActivity(17527): onStop

再进入主界面

10-25 21:28:06.895: I/MainActivity(17527): onRestart
10-25 21:28:06.895: I/MainActivity(17527): onStart
10-25 21:28:06.895: I/MainActivity(17527): onResume

以下是不同之处：

note2：

在主界面突然来电

10-25 21:28:55.285: I/MainActivity(17527): onPause

挂断电话结束返回主界面：

10-25 21:29:48.090: I/MainActivity(17527): onResume

盖世2：

在主界面突然来电

10-25 21:36:57.295: I/MainActivity(5634): onUserLeaveHint
10-25 21:36:57.295: I/MainActivity(5634): onPause
10-25 21:36:57.450: I/MainActivity(5634): onSaveInstanceState

挂断后返回：

10-25 21:36:59.020: I/MainActivity(5634): onResume

可能是刷的系统导致的不同，来电界面note2上估计是弹出的全屏toast，盖世2的系统可能是从底部冒出的其它半覆盖view所致。
